I’m new to using the BeagleBone Black
I designed a cape with a 7" TFT LCD along with support circuitry for my application. When I power up just my cape all of the LCD voltage levels are correct. When I plug my cape into the BeagleBone all of the voltage levels are correct but the LCD is just white and there is no booting activity.
What should I expect? If I purchase one of the ready-made LCD capes what should I expect when powering up? Does the BBB self boot?
